Hi soccerboy9,
I haven't had jaw surgery yet, so I can't be of any specific help. One thing to keep in mind is that, regardless of the surgery, every surgeon, anesthesiologist, surgical team, hospital, etc. does things a little differently. Unless you can find someone here that's worked with your surgeon etc. the run down of their day of surgery probably will not apply to you.
Sorry you're so nervous about all this. It might be worth talking to your surgeon, anesthesiologist, etc. to find out exactly what YOU need to expect. That way you would know specifics regarding what will happen.
I hope you feel better soon
